Title: Method of adjusting automatically control constant of pid controller
Inventor: IWASAKI MASATAKA
IPC: G05B13/02
Filed: 1985-11-20
Abstract: PURPOSE:To adjust automatically the control constant of a PID controller without troubling the manual operation of the operator by applying coordinate exchange and function approximation to a step response waveform of a process. CONSTITUTION:A step response output of a process is approximated into a linear lag system on new coordinates (t-y) taking an inflection point of said step response waveform using the output as y-axis and the time as t-axis as an original, the approximated equation obtained by said approximation is subjected to coordinate conversion on (t-y) coordinates to estimate a linear lag time constant T, a dead time L and a process gain K thereby deciding the optimum value of a proportional gain Kp, an integration time Ti and a differentiation time Td being PID controller parameters. In this case, n-set of observing points (n=2, 3, 4, 5...) are used to apply the linear approximation by the least mean square method to obtain the inflection point.

Abstract: PURPOSE:To efficiently correct a pin within a short time by providing at least four hammer systems possible to strike the head part of a nail situated just under a video camera by the operation of an actuator from above at an angle. CONSTITUTION:A video camera 205 is moved and stopped in the front of a nail 502 on a game board 500 surface by the operation of a manipulator 200, and detects the nail position by an image processing device 400. The position data of the nail is compared with the measurement data, and when the shift quantity and shift direction are out of an allowable range, a hammer system situated closest to the shift direction is selected from hammer systems 209a-209h, and its actuator is operated to strike the head of the failure nail and correct its curve. In this case, when the nail is excessively curved by the hammer system 209a, it is struck back by the hammer system 209e situated in the orthogonal position, whereby recorrection can be rapidly performed. Thus, the correction result is measured by the video camera 205 every strike of the nailhead by the hammer, and on the basis of the result, the hammer systems 209a-209h are repeatedly operated to correct the nail.

Title: Decoloration apparatus of colored water
Inventor: URUSHIGAKI KENJI
IPC: C02F1/00
Filed: 1994-10-26
Abstract: PURPOSE: To efficiently inject a decoloring material by operating the optimum injection amt. from the integrated operation value of the light absorption curve of colored water and a parameter such as the max. absorption wavelength or flow rate of the colored water according to a predetermined operation formula and injecting the decoloring material into the colored water in the optimum injection amt. CONSTITUTION: An operation means 1 considers the visible region of a person to set a wavelength range and calculates the light absorption curve of colored water to be decolored and uses the max. absorption wavelength, transmissivity, absorbancy and the relative difference between them as parameters to calculate the optimum injection amt. on the basis of the integrated operation value of the light absorption curve according to a predetermined operation formula. For example, since colored water is stable from the aspect of energy as the max. absorption wavelength becomes shorter even if the integrated operation value is same, it is necessary to allow a high concn. decoloring material to act. An injection amt. control means 2 controls the injection amt. of the decoloring material according to the calculated optimum injection amt.  By this constitution, the decorloring material can be injected efficiently.

Abstract: PURPOSE:To carry out easy desilverization or silver recovery by bringing a silver salt-containing aqueous solution into contact with metallic copper. CONSTITUTION:Silver is crystallized out merely by bringing metallic copper into contact with a silver-containing solution such as plating bath, photographic developing solution, copper electrolyte, etc., and desilverization can be efficiently carried out by removing the above crystallized silver by means of filtration treatment, etc. At this time, dissolved silver concentration can further be lowered by adding chloride prior to the contact with metallic copper. For example, 0.1g of pure hydrochloric acid content is added to 1l of silver-containing aqueous solution of copper sulfate containing 0.5mg/l silver, 50g/l copper, and 50g/l free sulfuric acid to undergo mixing, to which a metallic copper wire of 0.01mm diameter is added so that surface area becomes 0.2m<2> so as to carry out desilverizing treatment at room temp. for about 60min at a circulating rate of 100ml/min. Successively, the above aqueous solution is filtrated with a millipore filter, so that a low-silver (0.002mg/l silver concentration) aqueous solution of copper sulfate can be obtained.
